Application November 25, 1930 Serial No. 498,182

3 Claims. ,(Cl. 72101) angle beams such as used in the construction of furnace or flue covers or arches.

It is an object of the invention to provide a novel means whereby all of the bricks except one or more, can be placed in engagement with the lower supporting flanges of a beam after which one or more additional bricks or blocks of the same construction as the others can be attached securely to the beam so as to fill any gap which might remain in the row of bricks.

Another object is 'to provide a special fasten ing means which permits the placing of the last brick of a row either from below or above the arch.

A still further object isto provide a fastening device which is fully protected by the refractory brick or block supported thereby.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it beingunderstood that changes in the precise em,- bodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit ,of the invention.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing:

Figure 1 is a front elevation of a portion of an arch showing the space provided for the last brick of a row.

Figure 2'is a section on line 2-2, Figure 1 Figure 3 is a section on line 3--3, Figure 1, showing a block held in place by the special fastener constituting a portion of the present invention. v

Figure 4 is a perspective view of the fastener.

Figure 5 is a section through an arch beam provided with another form of fastener.

Figure 6 is a perspective View of the fastener shown in Figure 5.

Referring to the figures by characters of refence, 1 designates the usual I-beam used in the construction of a furnace arch, this beam being mounted on the wall 2 in the usual manner. The fire bricks or blocks 3 have recesses 4 in their upper portions so shaped as to receive the bottom flanges of the I-beam and thereby hold the bricks suspended. This is an old and well known construction. V

The present invention provides a means whereby all of the blocks or bricks can be applied to the beam after it has been positioned on the walls. This necessitates cutting away the bottom flanges of l-bfialll i at directly opposed points and for a distance equal to the width of one or more bricks, as shown at 5. A slot 6 is also provided in the Web of the beam above the cut-away portions.

The blocks or bricks are placed one at atime astride the beam 1 "where the flanges are cut away and then slid laterally onto the flanges. This operation is continued until there remains on the beam an uncovered space for the reception of one or more bricks or blocks, this being located directly above the cut-away portion of the beam, as shown in Figure 1.

Each one or more bricks forming the last of the series is then placed in engagement with a fastener'such as shown in Figure 4. This comprises a plate 7 bent to provide side flanges 8 with up- '(5 wardly extending wings 9. Each wing has its upper edge portion bent to form a curved lip 10 and normally these lips, which are extended in opposite directions respectively, are disposed substantially in alinement. $0,

The flanges 8 are inserted into the recess 4 in each one or more of the last bricks 3 and the wings 9 are placed astride the web of beam 1 where its flanges are removed. The brick or bricks are then forced to position in line with those previously placed, thereby moving the lips to positions where they will snap into slot 6 and support the brick or bricks in position.

Should it be desired to fasten the last brick or bricks from above the beam, two oppositely disposed angle brackets 11 can be placed in each recess 4 and lifted to opposite sides of the web of the beam. A bolt 12 can then be inserted through these brackets and slot 6 as shown in Figure 5.

What is claimed is:

1. The combination with an arch beam having flanges for supporting fire brick, said flanges being entirely cutaway at points in the beam, of means detachably secured to the beam for supporting a brick where the flanges are cut away, 0 said means including connected flanges, resilient wings thereon for receiving the beam therebetween, and means integral with the wings for engaging into the beam.

of fire brick supported by the flanges at opposite sides of said portion, thereby to form a gap between the bricks, a brick insertible upwardly into said gap, and means carried by the brick during said upward insertion for engaging the beam to support the inserted brick within the gap.
